Vitamin B12 Blood Test:

• Who should get this test: Patients with symptoms of vitamin B12 deficiency such as fatigue, weakness, numbness or tingling in the hands and feet, difficulty walking, memory problems, or mood changes, individuals with risk factors for deficiency like strict vegetarian or vegan diets, older adults, or those with gastrointestinal disorders that affect nutrient absorption.

• What's included in the test: The Vitamin B12 test measures the levels of vitamin B12 in the blood, which is essential for red blood cell production, neurological function, and DNA synthesis. Low levels of vitamin B12 can indicate a deficiency, while high levels may suggest an excess or certain medical conditions.

• Why someone would check this test: To diagnose vitamin B12 deficiency or excess, monitor treatment for deficiency, investigate symptoms of fatigue or neurological problems, evaluate abnormal levels of other blood tests like complete blood count (CBC) or methylmalonic acid (MMA), or assess the underlying cause of certain medical conditions such as anemia, neuropathy, or gastrointestinal disorders.

Vitamin D Blood Test:

• Who should get this test: Patients with symptoms of vitamin D deficiency such as fatigue, bone pain or weakness, muscle aches or weakness, or frequent infections, individuals with risk factors for deficiency like limited sun exposure, dark skin, older age, obesity, or certain medical conditions affecting vitamin D absorption or metabolism.

• What's included in the test: The Vitamin D test measures the levels of vitamin D in the blood, which is essential for bone health, immune function, and overall health. Low levels of vitamin D can indicate a deficiency, while high levels may suggest excess intake or certain medical conditions.

• Why someone would check this test: To diagnose vitamin D deficiency or excess, monitor treatment for deficiency, investigate symptoms of bone pain or weakness, evaluate abnormal levels of other blood tests like calcium or parathyroid hormone, or assess the underlying cause of certain medical conditions such as osteoporosis, rickets, or malabsorption disorders.

Folate Blood Test:

• Who should get this test: Patients with symptoms of folate deficiency such as fatigue, weakness, pale skin, irritability, or mouth sores, individuals with risk factors for deficiency like poor dietary intake, alcoholism, malabsorption disorders, or certain medications that interfere with folate absorption or metabolism.

• What's included in the test: The Folate test measures the levels of folate in the blood, which is essential for DNA synthesis, red blood cell formation, and cell division. Low levels of folate can indicate a deficiency, while high levels may suggest an excess or certain medical conditions.

• Why someone would check this test: To diagnose folate deficiency or excess, monitor treatment for deficiency, investigate symptoms of fatigue or anemia, evaluate abnormal levels of other blood tests like complete blood count (CBC) or vitamin B12, or assess the underlying cause of certain medical conditions such as megaloblastic anemia, neuropathy, or gastrointestinal disorders.

Ferritin Blood Test:

• Who should get this test: Patients with symptoms of iron deficiency or iron overload such as fatigue, weakness, pale skin, or abdominal pain, individuals with risk factors for iron deficiency or overload like heavy menstrual bleeding, gastrointestinal bleeding, or a history of iron disorders, or those with certain chronic diseases like inflammatory conditions or liver disease.

• What's included in the test: Ferritin is a protein that stores iron in the body, so the ferritin blood test measures the levels of ferritin in the blood. High levels may indicate iron overload, while low levels may suggest iron deficiency.

• Why someone would check this test: To diagnose iron deficiency or iron overload, monitor treatment for iron disorders, investigate symptoms of fatigue or weakness, evaluate abnormal levels of other blood tests like hemoglobin or hematocrit, or assess the underlying cause of certain medical conditions such as anemia or liver disease.

Calcium Level (Ca)

• Who should get this test: Individuals experiencing symptoms like muscle weakness, fatigue, bone pain, or kidney stones may need this test. It's also routine for those with certain medical conditions affecting the bones, kidneys, or parathyroid glands.

• What’s included in the test: Measures the amount of calcium in the blood, typically in milligrams per deciliter (mg/dL).

• Why someone would check this test: Checking for abnormalities in calcium levels is crucial as it plays a vital role in bone health, nerve function, muscle contraction, and blood clotting. Abnormal levels can indicate various medical conditions such as hypercalcemia (elevated calcium) or hypocalcemia (low calcium), which can be linked to issues like hyperparathyroidism, kidney disease, or vitamin D deficiency.

Magnesium Level:

• Who should get this test: Patients experiencing symptoms like muscle weakness, tremors, irregular heartbeat, or seizures, individuals with certain medical conditions like kidney disease or diabetes, those taking medications affecting magnesium levels, or those at risk of magnesium deficiency due to poor dietary intake or alcoholism should consider this test.

• What's included in the test: The test measures the amount of magnesium in the blood, typically conducted using a blood sample drawn from a vein in the arm. Magnesium exists in the body mainly in its ionized form, and the test evaluates both total and ionized magnesium levels.

• Why someone would check this test: Magnesium is crucial for various bodily functions, including muscle and nerve function, heart rhythm regulation, and bone strength. Low magnesium levels (hypomagnesemia) can lead to symptoms like muscle cramps, fatigue, and abnormal heart rhythms, while high levels (hypermagnesemia) can cause nausea, vomiting, and cardiac arrest. Monitoring magnesium levels helps in diagnosing deficiencies or excesses and guiding treatment to restore balance and prevent complications.
